Configuring duplicate message detection
To have the Carrier-enabled FortiGate unit check for duplicate messages, configure the duplicate threshold in an MMS profile, and select the MMS profile in a security policy.
All traffic matching the security policy will be checked for duplicate messages according to the settings in the MMS profile.
| The duplicate scanner will only scan content. It will not scan headers. Content must be exactly the same. If there is any difference at all in the content, it will not be considered a duplicate. |
The modular nature of the profiles allows you great flexibility in how you configure the scanning options. MMS profiles can be used in any number of policies, with different GTP profiles.
In a complex configuration, there may be many security policies, each with a different MMS profile. For a simpler network, you may have many security policies all using the same MMS profile.
